People With Deep Expertise - Mastery & Solitude

I have recently stepped away from engineering to pursue a passion of mine, which is talking to people who have a depth of knowledge in a certain field. The latest episode is with Felix Ó Murchadha, Professor of Philosophy at University of Galway, and we talked about loneliness, solitude, vulnerability, free will and death among many other things. Thanks to Felix for the time. The full episode is linked in the comments. If you know anyone who's spent a long time getting good at something, I'd like to hear from you!
